Oxford Castle, constructed in 1071 by Norman baron Robert D’Oyly, has a rich history spanning nearly a millennium. Initially a motte-and-bailey castle, it played a crucial role in the Anarchy of the 12th century. The castle later served as a prison from the 14th century until 1996, housing both criminals and political prisoners.

The castle’s paranormal reputation centers around several reported ghostly encounters. One of the most famous spectral residents is Mary Blandy, executed in 1752 for poisoning her father. Visitors have claimed to see her ghost wandering the castle grounds, particularly near the old prison wing.

Another frequently reported apparition is that of a monk, believed to be associated with the nearby St. George’s Chapel. Witnesses describe seeing a hooded figure gliding through the castle’s corridors and disappearing through walls.

The castle’s D-Wing, once housing the most dangerous criminals, is said to be a hotspot for paranormal activity. Staff and visitors have reported hearing unexplained footsteps, disembodied voices, and feeling sudden cold spots in this area.

In the castle’s crypt, people have reported seeing the ghostly figure of a man believed to be Marshal William Marshal, 1st Earl of Pembroke, who defended the castle during a siege in 1215.

The castle’s Well Chamber, descending 900 years into the past, is associated with reports of strange mists and orbs appearing in photographs.

Lastly, the castle’s mound has been the site of numerous ghost sightings, including reports of a woman in a white dress seen standing at its peak, gazing out over the city of Oxford.
